.SH DESCRIPTION
.sp
.LP
The \fBsettaskid()\fR function makes a request of the system to assign a new
task \fBID\fR to the calling process, changing the associated project \fBID\fR
to that specified. The calling process must have sufficient privileges to
perform this operation. The \fIflags\fR argument should be either
\fBTASK_NORMAL\fR for a regular task, or \fBTASK_FINAL\fR, which disallows
subsequent \fBsettaskid()\fR calls by the created task.
.sp
.LP
The \fBgettaskid()\fR function returns the task \fBID\fR of the calling
process.
.sp
.LP
The \fBgetprojid()\fR function returns the project \fBID\fR of the calling
process.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, these functions return the appropriate task or
project \fBID\fR. Otherwise, \(mi1 is returned and \fBerrno\fR is set to
indicate the error.
.SH ERRORS
.sp
.LP
The \fBsettaskid()\fR function will fail if:
.sp
.ne 2
.na
\fB\fBEACCES\fR\fR

.RS 10n
The invoking task was created with the \fBTASK_FINAL\fR flag.
.RE

.sp
.ne 2
.na
\fB\fBEAGAIN\fR\fR
.ad
.RS 10n
A resource control limiting the number of tasks or LWPs in the current project
or zone has been exceeded.
.sp
A resource control on the given project would be exceeded.
.RE

.sp
.ne 2
.na
\fB\fBEINVAL\fR\fR
.ad
.RS 10n
The given project \fBID\fR is not within the valid project \fBID\fR range.
.RE
